What is this?

Yet another bezier-curve library! Please view the demo here.

Installation

Install via bower: bower install rharel/js-bezier

The dist/ directory contains both a normal (bezier.js) as well as a minified version of the library (bezier.min.js). Include in the browser using <script src="bezier.min.js"></script>

Usage

Create

var controlPoints = [{x: 0, y: 0}, {x: 1, y: 1}];
var c = new Bezier.Curve(controlPoints);
c.complexity;  // 2

Evaluate

var controlPoints = [{x: 0, y: 0}, {x: 1, y: 1}];
var c = new Bezier.Curve(controlPoints);
c.at(0);  // {x: 0, y: 0, t: 0}
c.at(1);  // {x: 1, y: 1, t: 1}
c.at(0.5);  // {x: 0.5, y: 0.5, t: 0.5}

Draw

var controlPoints = [{x: 0, y: 0}, {x: 1, y: 1}];
var c = new Bezier.Curve(controlPoints);
var s = c.outline(t0 = 0, t1 = 1, precision = 0.5);
/**
 * s === [
 * 	{x: 0, y: 0, t: 0},
 * 	{x: 0.5, y: 0.5, t: 0.5},
 * 	{x: 1, y: 1, t: 1}
 * ]
